Resumen:
The mechanism for the poly-condensation event of conjugated polymers with ending 4-hydroxycoumarin has been proposed. It happened under H2SO4 acidic conditions only using enolic-coumarins without any substituent at third position. It was studied using Matrix assisted laser desorption/ionization time-of-flight (MALDI-Tof) mass spectrometry. Besides, some physicochemical properties were analyzed using Thermo-gravimetric (TGA), X-ray and UV-Vis analysis.
